Application led .Tune 8,1911'. Seial'lNo. 631,889.

To all whom t may concern.' A 1 Be it known that I, JULiUs Bniiilzzineiin, a

citizen of the United States, residing at bent and .intercurled by very 'slight grada-l Mount Vernon, in .the ,county ofv Westchester Y 'and State of NeWjYork, have invented certain new and uesful Improvements in Can- Heading Machines,V of which the following is a specification.

This invention relates tocan heading mac hines, in which the top or end portion of the can issecured to the bodyiportion thereof by what is known as tliedoubleseaming process.

rflic present contemplates additional improvements in the construction and operationv of the ma` chine shown and described by 'metin a,co.

pending applica-tion .filed June y7, 11911, Se

rial No. 631,752.` Inthisco-pending application, l have', shown and described a ma-` chine in which the parts to be sea'incd were rotated and supported by a rotatin-xghuck, with novel means for -bringi'ng-the'seaming rollers into' cooperative relation' to said chuck at the proper times and only when the" can parts were properly positionedin the machine, the Vseaming rollers being with# drawn from. the Work immediately after efectivexoperations thereof/and held in their comparatively remote' l and non-'cooperative positionsiit all otheiwtilfnes. j

in addition to a retentionof the improve ments lsetflortlr in said co=pending application, the principal object of the present in;4

vention is to provide means whereby the machine may be more rapidly operated and the capacity thereof materially increased with# out t'o the slightest extent -detracting .from its simplicity, efhciency and dependability.

To properly perform the seaming operation, it is necessarythat each seaming roller remain in contact with the partswhich are being seamed for from three to live relative revolutions'thereof when two' rollersfonly are employed, and from twdto four revolutions v'lien threeor more rollers are` employed, and that .the superposed flanges be .l tions.` Whei-e the seaining rollers are being reciprocated ,tol bring themfrom non-.co-

operative to cooperativepositions with re` lation to the chuck, and .vice versa, if this bodily movementrof the rollers is substan- .tially uniform', the' velocity must be very slow in order "that the scanning operation' invention more particularly may be properly performed, thus necessitating a loss of time in advancing the rollers to and retractingy the same from their effectively operative positions.

While the mechanism. shown and described both in this application and in my co-pendingapplication aforesaid in\ itself provides for a certain variance in the ve-4 locity of the moving rollers in advancing toy tion, in Which- Figure 1 is a central sectional side elevation of a machine embodying my invention; F 1g. 21s an enlarged horizontal section taken substantiallyon the line2-2 of Fig. l, and

Fig. 3 is an enlarged section taken substantially on the line 3-3 of Fig. 1. Fig. l is a id etailview in' side elevation ofthe mechanism for checking movement of the eccentric head, as hereinafter described.'

Referring now. to the drawings in detail, numeral 6 refers to the usual heavy frame supported upon the base 7. ln the upper e portion of this frame is journaled the main driving. shaft 8 provided with the usual fast and loose pulleys and 1,0, respectively, to which the power may be transmitted in the usual manner from any 4suitable source. In

the arms 11 and. 12, projecting forwardly from the frame, is journaled the vertical shaft 13.at the upper end of which is provided tlie bevel gear 14 in mesh' with the Asimilar gear 15 on the shaft 8. At the lower end of the. shaft 13 is mounted the chuck 16, of a size and configuration which adapts it -t'o fit snugly Withinv the correspondingly shaped depression inthe .can top or cover -and support the latter against the forces of the seaming operation. V p

'.'In the lovver. portion -of the `frame G is journaled-the shaft', driven fromthc shaft 8 by means ofthe belt 1S CQnDeCtngJthe pulley 119 onthe shaft `Swith the nulle 20,

drawings, forming a part of uns speciicaently rotatable sleeve 31 which terminates at on the shaft 17. At the other end of the shaft 17 is provided the bevel gear 21 1n mesh with the similar gear 22 at the lower end of the vertical shaft 23, suitably )ournaled in the socket 60 on the base of the frame and the sleeve 61 carried by the arms 24 and 25 projecting forwardly from the frame of the machine. This shaft 23 is vertically slidable in its bearings, and at4 the upper end thereof is provided a can-supporting platform 26 whic 1 is adapted to be yieldingly rotated by the shaft'23 and which isl 'arm 62 of said lever to actuate the lever 28 and correspondingly actu'ate the lever 30 through depression of the connecting-rod 29.

On the shaft 13 is mounted the independits lower extremity in the eccentric head 32.

`At the upper free end of this sleeve is mounted the disk 33, along the outer edge of the upper face of which is adapted to travel the roller 34 at the end of the lever 30. In the path of travel of this roller 34 on said disk 33, is provided the seat or pocket 35 into which said roller is forced to check rotation of said disk 33 and, consequently, rotation of the sleeve 31 and the eccentric head 32.

The` sleeve 31 is rotated by means of the gear 36 thereon in mesh with the gear 37 on the short shaft 3S journaled in the arm l2 of the frame. The shaft 3S is rotated from the horizontal shaft 39, suitably journaled in the frame, by means of the gear 40 in mesh with the worm 41 on said shaft 39 The shaft 39 is rotated from the shaft 8 by means of the belt 42 connecting the pulley 43 on the shaft 8 with the pulley 44 on the shaft 39. In order that the shaft 39 may bel rotated intermittently from the constanty rotating shaft 8, the pulley 44 is loosely mounted on the former, and is provided with a smooth face adapted to contact and cooperate with the contiguous face of the disk 45 fixed on said shaft 39, in the manner of the well-known friction clutch, rendered effective by means of the lever 46 which, when free to move under action of the tension spring 47, is adapted to force the friction face of the pulley 44 .against the friction disk 45 and yieldinglv effect ro' tation of the shaft 39.

The lever 46 forms one arm of a bell-crank lever the other arm 48 of which is normally held in a raised position by means of the pin 49 in the end of the 'arm 50 depending` from the lever 30. It will be apparent, therefore, Y

l`.that when this end of the lever 30 is depressed by the connecting-rod 29, the pin 49 will be lowered topermit the action-of the spring 47 and make the frictionclutch effective. lVhen the longer arm of the lever l,

30 is in its raised position, however, the pin 49 -will have raised the arm 48 and withdrawn the pulley 44 from contact with the friction disk 45, and the shaft 39 will not be rotated, this end of the lever 30 being raised under action of the more powerful tension spring 59 at the instant the seat or pocket 35 in the upper face of the disk 33 reaches the roller 34 at the other end of said lever 30 andsaid roller is forced therein to check rotation of said disk and of the sleeve 31, as more clearly shown in Fig. 4 and all as more fully described in my copending application aforesaid.

Journaled upon the eccentric head 32, at the end of the sleeve 31, is the carrying or supporting member for the'seaming rollers, this member preferably comprising a cylindrical portion 51, rotatively mounted on said eccentric head 32, and a disk portion 52 the edge of which is first upwardly and then inwardly turned to slidably engage the flange 53 at the end of the supporting sleeve 54 which is fixed in the arm 12 of the-frame. The upwardly and inwardly turned edge of the disk portion 52 of the carrying member may be said to provide an internal annular groove, and this groove is circumferentially of greater diameter than the diameter of the edge of the ange 53 at the end of the supporting sleeve 54. The supported carrying member, therefore, has a bodily movement laterally with relation to the liange on the fixed sleeve 54, such movement being limited, first, by the differencebetwecn the diameters of the flange and the groove and, second, by a pin 55 projecting upwardly from the disk portion 52 of said carrying member and into a substantially radiallydirected slot 56 inthe stationary an'ge 53.l

It will be apparent, therefore, as fully set i forth and described in my co-pending application, aforesaid, that when the sleeve 31 is rotated, the eccentric 32 will operate to impart amovement to the carrying member 52 which is a combination of reciprocation thereof in the direction of the slot 56 and oscillation about the pin 55 as a varying center. lVhile the double-seaming operation may ofttimes be con'ipleted .through the employment of two seaming rollers only, I have shown inthe drawings three rollers, 63, 57 and '5S-#the former indicated in dotted lines in Fig. 3. and each thereof heilig of common and well-known construction and iis ' successively or in turn advanced to and re# tracted from coperative position with reference to the chuck 16. Under in what may be termed normal conditions, with the platform 26 depressed, theroller 311 is in the seat or pocket 35 and the disk 33 is checked against rotation, in which .position all of the rollers' are held in positions -most remote froml the chuck 16. When the lever 27 is depressed to raise the platform 26 and engage the assembled can parts between saidplatform and the chuck' 16, theroller 34e is withdrawn from ,the pocket 35 in the manner described, permitting rotation of the disk 33.and the sleeve 31, which is then slowly rotated-bv the shaft 39 through the worm 41 in mesh with vthe gear /10 and the intermeshed gears 37V and 36, the friction clutch having been made operative by the releasing operation.

As set forth lin my co-pending application aforesaid, and as will even more clearly appear from the drawings and specification of another co-pending application, filed July 5, 1910, Serial No. 570,313, in which a corresponding construction and arrangement of parts of the seaming mechanism is shown and described in greater detail, the movement of each seaming roller, mounted Aand actuated in the manner herein shown and described, in advancing to and receding from the work, is at a variable speed which is at a maximum when the roller ishalfway between a position in which it is in v actual contact with the work and its relawhich the manual operations of removing a' tive position most remote therefrom, and at a minimum when in each of said-relative positions. However, the degree of eccentricity of the head 32 is necessarily so comparatively slight that this inherent speed variation may be materially augmented with resultant economy in time and consequent increase inthe capacity of thelmachine without too. greatlyA reducing. the time during headed can and adjusting in the mechanism the assembled lparts of a can to be headed .must be performed in making the operation of the machine as nearly continuous as 1 possible.v Therefore, in order to obtain the augmentedl variation in speed vreferred to, I mountthe gears 36and 37 eccentrically upon the shafts 31 and 38, respectively, as is clearlyshown in Fig. 2. From this figure, it will be apparent that when these eccentrically mounted gears are in the position shown, the gear 36 being driven by the gear 37, movement of the sleeve 31 will be relatively slow, whileV when these gears have been rotated through an arc of 180, the conditions will be reversed, and thesleeve 31 will be rotated at relatively much greate; velocity. These eccentric gears are so mounted upon their respective shafts, that they are in the position indica-ed in Fig. 2 when the seaming rollers are in rapid succession contacting with the chuck 16, under which con ditions the seaming operation is being performed and a relatively slow movement is required.. When the seaming operation has been completed, and the rollers are being withdrawn from the chuck 16, the speed of rotation of the sleeve 31, and consequently on the eccentric head 32, is-rapidly increasing, reaching a maximum when the rollers have been withdrawn to their positions of rest and at the start of the next succeeding operation. Similarly, the rollers will be returned to coperative positions relative to the chuck 16 at initially maximum and gradually decreasing velocities.

lThe spring 59, in tension between the end of the lever 28 and the arm 24, normally retains the platform 26 in its depressed pesition and the roller 3l1in the seat or pocket 35 in the disk 33, where it checks the sleeve 31 against ro-tationwith the seaming rollers 63, 57. and 58 Aattheir maximum distance from the chuck 16. In' this position, they are held until .another unseamed can is placed upon the platform 26,` and the lever 27 is again depressed to engage the can parts between said platform and the chuck 16, this operation releasing the sleeve 32 for rotation and operating the 4friction clutch to rotate the same through one revolution, as explained. It will b e`noted that the lever 27 may be released immediately after depression thereof, all of the parts being retained in position by the roller 3st which has been elevated to its track upon the upper face of the disk 33. When the seat or pocket 35 'specific' construction herein shown and de' scribed.
